5. Notes When Installing the Multipath Driver
5-1. Connection between the server and the storage system
When using a multipath configuration, the server and the storage system must be
connected after installing the Multipath Driver. If a multipath connection is
configured without installing the Multipath Driver, data in the storage system
may be corrupted.
If a multipath connection is already configured but the Multipath Driver is not
installed, stop all the applications that access the storage system until the
installation of the Multipath Driver is complete.
5-2. By installing the Multipath Driver, an initial RAM disk with the same name as
the current initial RAM disk is recreated.
5-3. After installing the Multipath Driver, the "by-path" name that was created by
the udev function as the storage system device name cannot be used.
When installing the Multipath Driver in an environment that uses the "by-path"
name as the storage system device, change all the settings that need to use the
"by-id" name before installation.
5-4. The Multipath Driver supports the Xen kernel that is provided by Red Hat
Enterprise Linux 5. Note that the Multipath Driver can be installed only in Dom0.
Do not install the Multipath Driver in DomU.
5-5. The Multipath Driver can be used with a KVM environment for Red Hat Enterprise
Linux 6 or Red Hat Enterprise Linux 7. Note that the Multipath Driver can only
be installed to the kernel of the host that installs KVM.
Do not install the Multipath Driver in a guest OS.
5-6. When the "!!! WARNING !!!" message is displayed during the "mpdpkgadd",
"mpdpatchadd" or "mpdsetup" commands, please refer to the Appendix-1.
5-7. Connections between a server using iSCSI Initiator and a storage system are
supported in the conditions that are described below. For the procedure on how
to start using an iSCSI connection, please refer to Appendix-2.

alias scsi_hostadapter mptbase
alias scsi_hostadapter1 mptspi
alias scsi_hostadapter2 xxxx <- add this line for xxxx driver
alias scsi_hostadapter3 mpdh <- add this line for mpdh driver
If the scsi_hostadapter number of the card is 9, number of mpdh must be 90.
Ex: for xxxx driver
alias scsi_hostadapter7 mptbase
alias scsi_hostadapter8 mptspi
alias scsi_hostadapter9 xxxx <- add this line for xxxx driver
alias scsi_hostadapter90 mpdh <- add this line for mpdh driver
Then execute "mpdsetup" command.
3-2. For SUSE Linux Enterprise Server 9 or SUSE Linux Enterprise Server 10
Please add the drivers of the card and mpdh into the INITRD_MODULES line of
/etc/sysconfig/kernel. The drivers of the card and mpdh must be consecutive.
